用花药培养筛选耐盐变异体培育小麦耐盐品种的新途径

A New Approach of Screening Salt-Tolerance Variants by Anther Culture to Cultivate Salt-Tolerance Wheat Variety

１９８６～１９９１年，应用花药培养与耐盐变异体筛选相结合的方法，对小麦耐盐育种新途径进行了探索。研究结果表明，在小麦花药培养中，选择加入一定浓度的ＮａＣｌ的筛选培养基，可以筛选出耐盐变异体，获得耐盐花培株系，经５个有性世代的鉴定表明，耐盐变异体的耐盐特性可以稳定遗传给后代。经筛选的花培株系中，耐盐特性能够稳定遗传的株系比例约占１／４，应用于育种实践，经多点鉴定，选育出了一批有实用价值的种质材料和优良品系。

The salt-tolerance variants of wheat were screened and the salt-tolerance lines were obtained by adding NaCl into the medium in the anther culture. The results of observation for 5 generations showed that about 25 percent of the lines could stably propagate their salt-tolerance ability to their progenies.So far a lot of salt-tolerance germplasm and lines that could be used in wheat production had been obtained by this method.A new approch for breeding salt-tolerance cultivars of crops was provided in this study.
